To determine

To find :the sum for $-10+\left(-12\right)$ .

Answer to Problem 40E

The sum for $-10+\left(-12\right)$ is $-22$ .

Explanation of Solution

Given : the expressionis $-10+\left(-12\right)$ .

Calculation: for find the sum of this expression subtract the opposite of the $\left(-12\right)$ from $-10$ ,

  $\begin{array}{l}-10+\left(-12\right)=-10-12[theoppositeof\left(-12\right) is\text{ 12}]\\ -10+\left(-12\right)=-22\text{ [subtract]}\end{array}$

Hence, The sum for $-10+\left(-12\right)$ is $-22$ .
